LAUNDRY-STOVE.

Specification of Letters Patent.

Patented May 12, 1914.

Application filed January 6, 1914. Serial No. 810,581.

To all whom it may concern Be it known that I, WONG I Gone, a citizen of the Republic of China, and a resident of West Hoboken, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Laundry-Stoves, of which the following is a specification.

This invention relates to improvements in laundry stoves, and especially to improvements in the grates of such stoves and the means of operating said grates.

The stoves to which the invention is especially applicable are of that class which are used for heating laundry irons; and the especial purpose of this invention is to pro vide shaking and dumping grates for such stoves so constructed and arranged, and so combined with said stoves, that the fire on the grates can be kept bright and fresh for considerable periods of time without dumping and by merely shaking the grate, and that when it becomes necessary to dump the fire or the materials which have accumulated on the grate, said grate can be readily dumped, the stove cleaned, and the grate re turned to its normal position to receive fresh fuel.

Details of the invention will be evident from the description hereinafter given, taken in connection with the drawings which accompany the specification, and whereof- Figure 1 is a broken vertical section, partly in elevation, of a laundry stove equipped with my said improved shaking and dumping grate; said grate being indicated in its normal position by solid lines, and in its dumping position by dotted lines. Fig. 2 is a horizontal section and plan, on the plane of the line 2-2 of Fig. 1, and as seen from above; Fig. 3 being a front edge view of said grate. Fig. 4: is a horizontal section and plan, on the plane of the line el4= of said Fig. 1, and as seen from below; Fig. 5 is a broken plan view of a modification showing a slotted grate extension, or handle; and Fig. 6 is a broken elevation of a stove showing guiding lugs cooperating with the slots in said extension or handle.

Referring to Figs. 1 to 4. inclusive, A is a sheet metal laundry stove of any usual construction adapted to heat laundry irons, and preferably of circular cross section, B is the ash pit of said stove provided with a front door opening 6, and being preferably shaped as a frustrum of a 00116, B being the base equipped with legs cl. The flange A is recessed to support the laundry irons in the usual manner.

My preferred grate is constructed and arranged as follows: Said grate comprises two principal members, viz.: The main dumping grate 1, and the auxiliary sliding grate 2, each of said grates being provided with suitable grate bars 3, 4:, respectively, and being constructed of any suitable metal, as cast iron. Said main grate l is provided with hinge pins 55, which fit loosely in sockets in the inner flange a. of said stove A. Said main grate 1 is provided with an internal opening 10, as seen in Fig. 4, which said opening greatly facilitates the shaking of the grate, as will be hereinafter further explained. Said auxiliary grate 2 slides on guide lugs 66, 77 formed on the under side of said main grate 1, and when said grate 2 is in its normal position, (Fig. 2), the rear ends of parallel rearwardly projecting bars 88, with which said auxiliary grate is provided, engage under said flange a of the stove, whereby said auxiliary grate 2, as well as said main grate 1, is held in the normal horizontal position. By said construction, it will be evident, said auxiliary grate 2 may have a to-and-fro motion under the said main grate 1, and to limit the amount of said motion of said auxiliary grate 2 a stop pin 12 is provided on said grate 2 engaging at the several limits of its motion, with sockets 13, 1a in said main grate 1. Said grate 2 is provided with a forward extension or handle 16, normally projecting out through said door opening Z) and being provided with an eye 17 adapted to be engaged by a poker to shake the grate, and said extension or handle, (hereinafter briefly termed. handle) is provided with a slot 18, which slides on a headed pin 19 fixed on the front part of said ash pit B. At its front end, said slot 18 is connected with a recess 20 in which normally rests the head of said pin 19, and at a proper position said slot 18 is widened, as at 21, Fig. 1, so as to permit said grate handle 16 to swing down over said bolt head, when the grate is being dumped.

It will be manifest from the foregoing description that my construction provides a combined dumping and shaking grate which operates in the following manner: In the normal position of the parts the auxiliary grate 2 will be in the rearward position, as

shown in Fig. 2, and the grates will be held very securely in their normal horizontal position. Should the fire require shaking, then the handle 16 of said grate 2 will. be engaged by a poker, or any suitable implement, and said auxiliary grate 2 will be drawn forwardly and outwardly, whereby the said opening 10 down through said main grate 1 will be left unobstructed, and more or less of the ashes, clinkers and burnt out coals will drop therethrough into the ash pit; and now the attendant, by rapidly reciprocating said auxiliary grate 2 forward and back will thoroughly shake the fire and render the same fresh and bright, By thus shaking the grates, the lire will be maintained fresh and hot for a suitable period of time without dumping. In the aforesaid operation of the auxiliary grate, it will be manifest, that said auxiliary grate merely moves to-and-fro by reason of the aforesaid guide lugs 66, 'T7 and the head pin 19, without being dropped below its normal plane. Whenever it is necessary to dump the fire, or the mass of fuel on said grates 1 and 2, then said auxiliary grate will be drawn forward to such a position that the ends of said bars SS being withdrawn from under the said flange a, and that the aforesaid widened part 21 of said slot 18 will be in line with the head of said bolt 19; and in this position said auxiliary grate and said main grate can be tilted together on the hinge of said main grate down to the position indicated by dotted lines in Fig. 1, whereby, said fire or fuel will be dropped into the ash pit B, the said fire or fuel being readily raked off said grates into said ash pit. When said grates are cleaned, they can be restored again to their normal horizontal position by lifting said handle 16 until said bolt head again passes through said widened part 21 of said slot 18, and then'said handle 16 with its auxiliary grate will be pushed rearwardly to the position shown in Fig. 2, in which position said auxiliary grate, as well as said main grate, will be again held in the normal horizontal position.

Various modifications of the construction may be devised without departing from my substantial invention, one of such modifications being illustrated in Figs. 5 and 6, wherein, said handle 16 is provided with slots 2-1, positioned and arranged to pass down between lugs 26, which are secured at suitable locations near the front of said ash pit B, when it is desired to dump the grates. In the normal position of the parts, said handle 16, as well as the said grates 1 and 2, are held in horizontal position because the unslotted portion of said handle 16 is then supported by said lugs 26. To dump the grates, said handle 16, together with the grate 2, is drawn outwardly until said slots 2% are in line with said lugs 26, when said handle 16, together with said grates l and 2, may be lowered to the dumping position. To restore the parts to their normal position, said handle 16, together with said grates 1 and 2, is lifted to the horizontal position, and then said handle 16, together with said grate 2, is pushed inwardly until the unslotted part of said handle is supported by said lugs 26. It is manifest that by arranging the said bolt 19 with a vertical ring-shaped head, provided with an eye to be engaged by a poker or other implement, so that said bolt 19 can rotate about its axis, then said head being normally arranged across the slot in the grate handle 16, by merely turning said bolt ninety degrees, the bolt head will allow said slotted handle 16 to descend so as to drop the grates; and

it will be manifest that other variations in the construct-ion may be made without departing from my invention.

Now having described my innorovements, I claim as my invention.

The combination in a combined sliding and dumping grate of a laundry stove of a main dumping grate 1 having an internal aperture 10 and being pivoted in said stove to swing downwardly when desired, an auxiliary grate 2 carried by and reciprocating on said main grate 1, said auxiliary grate being arranged to close said aperture 10 in the rearward position of said auxiliary grate 2, and to leave said aperture 10 open in the forward position of said auxiliary grate 2, rearward projections on said auxiliary grate 2 adapted to engage said stove, and hold both said grates against dumping while said auxiliary grate is in its rearward position, and to permit said grates to dump when said auxiliary grate 2 is not in its rearward position, a forwardly projecting handle 16 on said auxiliary grate and means on said stove engaging said handle 16 and adapted to prevent the dumping of said grates except when said auxiliary grate 2 is in one forward position and to permit said grates to be dumped when said auxiliary grate is in that one forward position, substantially as described.

Signed at New York city, in the county of New York, and State of New York, this 3rd day of January, A. D. 1914.
